At `30^(@)`C, a lead bullet of 50 g, is fired verticaly upwards with a speed of 840 m/s. The specific heat of leasd is 0.02 cal/`g^(@)`C. On returning to the starting level, it strikes to a cake of ice at `0^(@)`C. Calcualte the amount of ice melted (Assume all the energy is spent in melting only)

A 50gram lead bullet, specific heat 0.02 is initially at 30^(@) C. It is fired vertically upwards with a speed of 840 m// s . On returning to the starting level, it strikes a cake of ice at 0^(@)C . How much ice is melted ? Assume that all energy is spent in melting ice only. Take latent heat of ice = 80 cal. // gram.

A 50 g lead bullet (specific heat 0.02 ) is initially at 30^(@)C . It is fired vertically upward with a speed of 840 ms^(-1) . On returning to the starting level it strikes a cake of ice at 0^(@)C . How much ice is melted ? Assume that all energy is spent in melting only. Latent heat of ice =336 j g^(-1) .

A 50 gm lead bullet (sp. Heat 0.020 cal//g) is initially at 30^(@)C . It is fired vertically upward with a speed 84 m//s On returning to the starting level, it strikes a slab of ice at 0^(@)C . (Axx100) mg of ice is melted. Find the value of 'A' .

When 1 g of ice melts at 0^@C

80 g of water at 30^@C are poured on a large block of ice at 0^@C . The mass of ice that melts is
